<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>First I thought a restrictor plate between the TB
and plenum, then thought I'd have to experiment with different diameters. Then
I thought a throttle stop maybe. then I thought to use some really dirty
filters (just a joke) ...I just have to make sure theres only 220-240 G/S of
air maximum. what does anyone think?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT size=2>Ya might be overthinking it. The motor will use more
than the 240grms/sec., and beyond that level it doesn't see any
increase. So just be conservative with the timing, and you should be
OK. For 320 Hp personally I wouldn't get inna twist over that. Now,
crank it up to 375, and then we would need to readdress it. Your losing
resolution which is power, but now your not hunting for max HP.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I guess I could even pull the spark back
far enough (flat?) so the thing only makes 85% of its power but they say
banging the pistons too much in the wrong side of the stroke isn't really
good. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Why/Who said that?. Within reason, I can't
off hand see a problem. Assuming mixture is right. If ya really
are worried run an EGT..</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The 22# injectors are good (with some FP) to like
325 hp- which is fine for now, and maybe fine for good.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>This all may sound strange - what it is is that
I'll have the bottom end installed waay before I have the supporting stuff all
set up, and am curious what the thing will do (E.T., as a study) with (nearly)
stock intake / exhaust parts on a 10.3:1 383. </FONT></DIV>

<DIV><FONT size=2>Used to be a copy of drag strip plus in the archives, was
within the converter slippage as right with my F-bod.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Maybe the stock intake parts are going to do the
restriction job for me just the way they are ;-?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2><FONT face=Arial size=2>lookin for creative,
safe, effective "use the ECM settings to reduce the power" solutions, or any
other comments.... ECM rooted, of coarse ;-) </FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2>Mechanically every engine has it's limit. Sometimes
just using the ecm as designed ain't that bad. As I recall this was
about a 6 PSI S/C application right?.</FONT></DIV>
